In order to use all that the vine generously offers, the spent pomace, from which the alcoholic and aromatic potential has been extracted, is dried to separate the grape skins from the grape seeds. Rich in cellulose, the former are used by the same distillery as a renewable source of bioenergy to produce the steam needed to power the distilling process. The latter, on the other hand, are used in the oil industry to produce one of the healthiest cooking oils in existence, valued by gourmands.
The thermal energy requirements for producing the steam necessary for distillation are met by using the grape skins which are dried after distillation. A by-product of the main production process is thus used as a renewable source of bioenergy, avoiding the use of fossil fuels (non-renewable resources) to power the boiler. Exhaust fumes from the combustion in the boiler and the desiccation of the pomace are treated in a cutting-edge plant that uses innovative technology to minimize the release of emissions into the atmosphere, fully complying with extremely strict governmental limits. .
Most of the distillery’s electricity requirements are met by the treatment cycle for residual liquid from distillation, which, once having undergone anaerobic digestion, generates biogas that, powering a special green engine, is transformed into electricity to power the company’s equipment replacing the alternate energy derived from fossil fuels available in the national grid.. Anaerobic treatment and subsequent aerobic treatment of the residual liquid, their concentration and drying improves environmental compatibility, breaking down nearly all of their original organic content and minimizing waste.
At the Mestrino production plant where distillates are packaged and distributed, the installation of two photovoltaic systems to generate electricity from a renewable source ensures the company’s near self-sufficiency.
